1 Claim.

The present invention relates to new and useful improvements in fasteners for screens and storm windows and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction and arrangement whereby screens and storm windows may be expeditiously secured in position and released from inside the building.

Another very important object of the invention is to provide a screen or storm window fastener of the aforementioned character which will not mar or damage the window frame or sashes in any way.

Other objects of the invention are to provide a screen or storm window fastener of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in front elevation, showing a window screen secured in position through the medium of fasteners constructed in accordance with the present invention.

Figure 2 is a view in horizontal section, taken substantially on the line 2-2 of Fig. 1.

Figure 3 is an elevational view of one of the fasteners, showing the device in use.

Figure 4 is a perspective view of one of the fasteners.

Referring now to the drawings in detail, it will be seen that the reference numeral I designates a window frame of conventional construction which includes a blind Stop 2. Mounted in the window frame I is a screen which is designated generally by the reference numeral 3, said screen including a frame 4.

The embodiment of the present invention which has been illustrated comprises a tapered screw 5 which is mounted in the inner side of the screen frame 4. Mounted on the screw 5 is a clip 6 of suitable resilient metal comprising a foot portion 1 engageable with the screen frame 4. The clip 6 further includes a lip 8 on one end which is engageable behind the blind stop 2 in the manner shown to advantage in Fig. 2 of the drawings. The portions 1 and 8 of the clip 6 are connected by a substantially diagonal intermediate portion 9.

Of course, the portions 7 and 9 of the clip 6 have formed therein aligned openings which accommodate the screw 5. Pivotally mounted for swinging movement on the free end portion of the screw 5 is a bifurcated cam lever Ill. The cam lever I0 is engageable with the intermediate portion 9 of the clip 6 for clamping the lip 8 on the blind stop 2 thereby firmly securing the screen frame 4 against said blind stop. This, also, is shown to advantage in Fig. 2 of the 10 drawings.

It is thought that the manner in which the fastener functions will be readily apparent from a consideration of the foregoing. As many of the fasteners as may be necessary or desirable may be used for each window. To mount the fasteners on the spring frame 4 the screws 5 are inserted through the openings provided therefor in the portions 1 and 9 of the clip 6 and said screws are then threaded into said screen frame, 20 the cam levers I0 being utilized to turn said screws. The openings in the feet I are small enough to cause the tapered screws 5 to seat tightly therein for securing the clips 6 firmly in position on the frame 4, while the openings 25 in the diagonal intermediate portions 9 of said clips are sufficiently large to allow free movement of said portions 9 on the screws. With the lips 8 engaged behind the blind stop 2 the cam levers ID are swung to the position illustrated in full lines in Fig. 2 of the drawings thus clamping said lips firmly against said blind stop thereby securing the frame 4 thereagainst. When it is desired to remove the screen it is only necessary to swing the cam levers H! to inopera- 85 tive position and loosen the screws 5 in the feet I after which the lips 8 may be swung from behind the blind stop 2 or, if desired, the fasteners may be removed from the screen. It will thus be seen that the screen or storm window may be secured in position and released from inside of the building. Also, the construction is such as to interfere in no way with the operation of the window sashes.

It is believed that the many advantages of a screen or storm window fastener constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A screen fastener comprising a clip of resilient metal having a lip at one end to engage a fixed member, an inturned foot at its opposite end to engage a movable member, and. an intermediate arcuate portion extending diagonally between said lip and foot, said foot and intermediate portion having aligned openings formed therein, said lip and foot extending in spaced parallel planes, a tapered screw passing through said openings and threaded into said fixed member,

the intermediate portion and lip being adjustable and movable on said screw, and a cam lever pivotally mounted on the end of said screw having adjacent angularly arranged coacting faces adapted to conform with the surface of the intermediate portion of the clip and to lie in parallel contact therewith when. said clip is in locked and in unlocked position.
